Be it known that I, CABLYLE MAoI-IARG, a citizen of the United States, residing in Hinsdale,4 county of Du Page, nois, have invented a certain new and useful Improvement in Reenforced Bedv Springs, and declare the followin to be a full, clear, and exact description o? the same, such as will enable others skilled in the art to which it pertains to 'make and use the same, reference being had to the accompanying draw# ings, which form a part of this specification.

A very common form of bed spring is one in which the spring body is composed of many coiled springs arranged vertically side the upper convolutions of the springs being cross connected from one spring to another by means of small coiled.V springs that tend to hold the main springs upright and yet permit them toyield freely. One objection to bed springs of this kind .1s that they yield too readilyl under a lateral pressure against the edge t ereof, even when the upper convolutions of the outermost springs are connected to a light frame extending entirel around the structure. An object o the present invention is to improve bed springs of this general t pe soateral the edges, without detractas to make them more resistant to pressure against structure under pressures in the vertical direction. e

In carrying out my@ invention I brace the marginal portions of the structure by fastening theu per most line o springs to the adjacent inner springs, namely to the springs of the next inner: line or row.

Therefore, viewed in one of its aspects, my invention may be said to have for its objectto produce a simple and novel means vfor connecting corresponding convolutions of t`wo springs in suc relative movements of suc convolutions from or toward each other in the pla-ne thereof, while permitting relative movements out of said plane.

a wa as -to prevent N The various features of novelty whereby will hereinmy invention is characteriz be pointed out with particularity in after the claims; but, for a full understanding of Y detailed invention and of its objects and advantages, reference may be had to the lfollowing descriptionjtaken in connection State of Illilocking clip convolutions of the outer` the preferred means of attaching the upper convolution of an outer spring to the upper convolution of an inner spring; Fig. 4 is a.

section taken approximately on line 4--4 of f Fig. 3; Fig. 5 is a perspective view of the shown .in Figs. 3 and 4, the dotted line showing the bent position vof the looped end of the clip in the Icompleted bed spring; Fig. 6 is a view similar to Fig. 3 showing a modified connection; Fig. 7 1s a section taken approximately on line 7-7 of Fig. 6; Fig. 8 is a view similar to Figs. 3 and 6 showing a still further modification; and Fig. 9 is. a section taken approximately on line 9-9 of Fig. 8.

Referring tothe drawin s, 1 represents a base or frame of any usua or suitable construction on which are set vertical coiled springs 2 and 3, also of any usual or suitable construction, those illustrated being of the type inwhich the convolutions increase in diameter from the bottom toward the top.

In the space bounded by each group of four springs are placed small cross springs 4, there being two of such cross springs arranged in right angles to each other in each such space; each spring extending between and being connected with the upper con volutions of two of the main springs. Extending around the up er portion of the spring body is a li ht ame 5 that is fastened in any suitab e way to the upper convolutions of the outermost springs. e construction as described up to this point is old and well known and, while m invention is most advantageously applie to this particular form and arrangement, it is also .suitable for use in other types of bed springs or the like.

When a lateral ,pressure is exerted at any point on the light frame in a structure 4of little resistance to inward I have found th t if each of the outermost springs,

excepting'perhaps those atl the' four 'corners of a rectangular structure where there is inherent rigidity, has its upper convolution connected to the adjacent spring of the next inner row by a stiff tie or strut, sothat the upper convolutions of any outer spring and the corresponding inner spring must move in unison in the plane of those convolutions, any lateral pressure on the light frame 5 is distributed and resisted so as to overcome the .objection of unduly large deflection. These reenforced connections can conveniently be made by bending the upper convolution of one of the two springs to produce a radially-projecting arm whose free end is then securely fastened to the upper convolution of the other of the two springs. The arm may be a part of either the outer spring or the inner spring; and, for the sake of illustrating both arrangements, I have shown them both in Fig.'2.

The details of the special connection between the springs of the two outer rows, in

'its preferred form, are best shown in Figs.

3 to 5. Referring to these figures, in which 2 and 3 are the springs, the upper convolution of the spring 3 has apart 6 bent laterally to form a short U-shaped arm, the outer looped end being bent downwardly as indicated at 7. This arm iS laid upon the upper convolution of the spring 2, with the depending portion 7 bearing against the inner side of said convolution. The two springs are then fastened together by means of a U-shaped clip 8 having at the free ends of its arms hooks 9 and 10 that lie in a plane transverse to the length of the clip and are preferably arcs of a circle somewhat longer than 180 degrees; the internal diameter of the hooks being the same as that of the wire of which the main springs are made. When two s rings are to be fastened together, the cl1p is inserted between the two side members of the arm6, with its looped end down, underneath the wire of the upper convolution of the spring 2 and through the depending looped end '7. The hooks .9 and 10 overlie the horizontal portions of the side members of the arm 6 and may be sprung upon .these side members so as partially to surround the latter. The inner end of the clip is then bent down, as indi-- cated at -11 in dotted lines in Fig. 5, and in full lines at Fig. 4. As the end of the clip 11 is bent down the hooks are drawn laterally as far as they can go, so that a secure tie between the arm 6 and the upper convolution of the spring 2 is obtained.

If desired, the fastening of the arm on one spring to the other spring may be effected without a clip. Thus in Figs. 6 and 7 there is shown an arm 12 which is V-shaped, rather than U-shaped. This arm is made long enough so that when it is laid upon the upper convolution of the spring 2, it may be bent underneath the same and then up so that the wire of the upper convolution of the spring is completely encircled. By making the arm 12 V-shaped, the narrower closed end is free to pass up between the sidemembers of the arm.

In Figs. 8 and 9 there is shown an arm 14:, similar to the arm 12; but, instead of passing this arm above the upper 'convolution of the spring 2, I pass it underneath the same, and then bend the closed free end upwardly across the top of the upper convolution and then down between thevside members of the horizontal portion of the arm.

'Ihe arms in each case are preferably given a jog in the vertical direction so as to permit the upper convolutions of the two springs to lie in the same. horizontal plane when fastened together. In the arrangement shown in Figs. 3 and 4 this jog, indicated at k15, is in the upward direction, 'as is also ythe jog 16 in Fig. 7.* In Fig. 9, since the arm passes underneath the wire of the upper convolution of spring 2, th jog 17 isl in the downward direction.

While I have illustrated and described with particularity only a single form of my invention, with slight modifications, I do not, desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms and arrangements that come within the definitions of my invention constituting the appended claims.
